We are pleased with our Oster Pro 1200 blender so we ordered the food processor attachment.  Tried to make cole slaw using the circular shredder/grater disc.  Pushing cabbage & carrots down against the shredder/grater disc attachment, the food just deflects the disc and the processor doesn't work.  Tried putting the food into the processor with the bottom blades running, the motor is so powerful it turns the cabbage and carrots into a powder even using the slowest speed.  Finally an idea:  I cut the cabbage and carrots into 1 inch pieces and put them in the processor BEFORE I turned it on, using the bottom blades, not the circular shredder/grater.  Then I close the top and just barely touch the "pulse" button for about a millisecond.  Two or three of these millisecond pulses and I had the makings of cole slaw!  Success!  Suggest you put something on your website on this.
